CDC341DW

Overview

The CDC341DW is a single-circuit fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It provides an 8:1 output ratio from a single TTL input to eight TTL outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum frequency of 80 MHz. It is housed in a 20-SOIC package with a width of 7.50mm and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Single circuit providing 1-to-8 fanout distribution
• TTL input and TTL output compatibility
• Maximum operating frequency of 80 MHz
• Surface mount 20-SOIC package

Applications

• Clock signal distribution in digital systems
• Fanout buffering for high-speed logic circuits
• Timing reference distribution in embedded hardware

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to confirm availability and exact specifications. Ensure that the 20-SOIC package dimensions and thermal characteristics match the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a single-ended TTL source requires driving multiple TTL loads with minimal propagation delay. Confirm that the system power supply remains stable between 4.75V and 5.25V. Verify that the ambient operating environment stays within the 0°C to +70°C commercial grade range.

Part Context

This component belongs to the family of clock buffers and drivers produced by Texas Instruments. It serves as a dedicated solution for expanding clock signals in synchronous digital designs where standard logic gates may not provide sufficient drive strength or timing performance.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified equivalent parts. Cross-reference pinouts and electrical parameters carefully if considering alternatives from other manufacturers.
